Dust and pollen filter
The dust and pollen filter with activated charcoal reduces the level of impurities in the outside air entering the vehicle.
The dust and pollen filter must be changed regularly to avoid impairing the performance of the air conditioning system.
The dust and pollen filter must be changed more frequently than stated in the service schedule if the efficiency of the filter declines prematurely due to the vehicle being used in areas with high levels of air pollution.

NOTICE
If the cooling system is switched off, the outside air that is drawn into the
vehicle is not dehumidified. To prevent the windows misting over, Volkswagen recommends
that you leave the air conditioning (compressor) switched on. Press the
button. The indicator lamp in the
button must light up.
Maximum heat output, which is needed to defrost the windows as quickly as possible, is only available when the engine has reached its operating temperature.
Keep the air intake slots in front of the windscreen free of snow, ice and leaves to ensure heating and cooling is not impaired, and to prevent the windows from misting over.
After starting the engine with a discharged vehicle battery or after an emergency start, system settings (time, date, personal convenience settings and programming) may have been changed or deleted. Check and correct the settings as necessary once the vehicle battery has been sufficiently charged.
